摘　　要：随着建筑工程的不断发展,对传统防水层粘接性能的要求日益提高。目前传统防水层材料面临粘接强度不足以及长期在潮湿环境中粘接性能下降的问题。为进一步改善防水层与基层间的粘接性能,提出了2种对沥青基防水卷材进行表面改性的仿生策略:一是根据贻贝等海洋生物的粘附机理,在卷材表面吸附多酚分子,使其与基质表面产生氢键等多种相互作用力;二是受壁虎等爬行动物脚掌图案的启发,将卷材表面图案化,通过凸起、凹陷设计,增大卷材与基层的接触面积和摩擦力。剥离测试结果表明,2种仿生策略均能有效提高卷材与混凝土的界面粘接力。With the development of construction engineering,the requirements for the bonding performance of waterproof layers are increasing.At present,waterproof layer materials are facing problems such as insufficient bonding strength and decreased bonding performance in humid environments for a long time.To further improve the bonding effect between the waterproof layer and the substrate,we propose two biomimetic strategies for surface modification of asphalt based waterproof sheets.Firstly,based on the adhesion mechanism of marine organisms such as mussels,polyphenol molecules are adsorbed on the surface of the waterproof sheets,causing them to generate various interactions such as hydrogen bonds with the substrate surface.Secondly,inspired by the foot patterns of reptiles such as geckos,the surface of the waterproof membrane is patterned,and the contact area and friction between the waterproof sheets and the substrate are increased through a convex and concave design.The peel test results indicate that both strategies can effectively improve the interfacial bond performance between waterproof sheets and concrete.
